Intake boot at throttle butterlfy - re/re a pain?

Hi guys

I am clearly bored and looking at stuff to "fix" 8)   The large intake boot beween the intake and throttle butterfly on my 6.9 looks mighty tired.  Also, I see a second band clamp below the top one, which does not look spec to me, so I can only guess a previous tech thought it a good idea to add another clamp, which of course will lead to shenanigans to get off :o Not sure why they would do this but I digress...

I checked the W126 boards and it looks like the top band clamp has some old school type ratcheting screw so you can tighten from above.  Some folks state that this design is a PITA to replace so likely I think a large enough hose clamp will do the jobby, no?  Some guys even use a BMW M3 clamp on there, uhm no...

Any folks done this jobby with success recently?  In my experience this looks like a "simple" job, but this could lead to a nightmare ::)

daantjie,

you are digging into my late fall job. I plan to take of the entire air intake and replace all the rubber parts and gaskets. A US 6.9

I'm in discussions with Elring about the two air intake gaskets left and right.

I haven't studied the area you are addressing in detail. Look forward to following this thread.

Sorry I can't help you at the moment ...

YES I'VE DONE IT AND IT'S A REAL PITA!
You will need to think about how to get around the top band...you will need a top drive.
